Hi,

I must be missing something very basic here.

I have a parent template and I am calling a sub template like…

\<%= render( :partial =\> “window\_title\_bar”, {“heading” =\> “Product  
Details”}) %\>

and in the sub template (\_window\_title\_bar.rhtml), i am doing

Heading: \<%= heading %\>

but I am getting syntax error in the master template at line

\<%= render( :partial =\> “window\_title\_bar”, {“heading” =\> “Requirement  
Details”}) %\>

Any help is appreciated. Thanks in Advance.

```
 > render( :partial => "window_title_bar", {"heading" =>

```

“Requirement Details”})

You forgot the ':locals =\> ’ part. It should read:  
\> render( :partial =\> “window\_title\_bar”, :locals =\> {“heading” =\>  
“Requirement Details”})

You need to specifically tell the render method that you are passing  
in local values for the partial template to use:

\<%= render( :partial =\> “window\_title\_bar”, :locals =\> {“heading” =\>  
“Requirement Details”}) %\>

I also recommend using symbols whenever you can, so I would actually  
use this version:

\<%= render( :partial =\> “window\_title\_bar”, :locals =\> {:heading =\>  
“Requirement Details”}) %\>
